X-Git-Tag: accepted/trunk/20130322.191538~4137
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ec2f012870ad64a16921f53f65a691592067bbce;p=platform%2Fupstream%2Fperl.git

mktables: Add info giving specials hash name

mktables creates %utf8::SwashInfo in each table it generates, giving
some info about the table.  Add an entry to this for tables that have
a hash of special mappings, giving the name of that hash.
